These Tricky Trees align with the Skills from Core Knowledge. Please print each unit then bind the trees to make a book. Rings or a book binder work best. I would print the trees on card stock. Then print the leaves on green card stock and laminate. Last I would put an envelope on the back so that the leaves can be stored next to there tree.
My students have really enjoyed using them. They could be used in daily 5, shelf work, or centers. The tricky trees are from Core Knowledge Unit 5-7. They are not introduced until unit 5.
